IMPROVEMENT IN BOlLER-FEEDERS.

Specification forming part of Letters Patent No. 164,595, dated June 15,1875; application filed May 17, 1875.

To all whom it may concern Be it known that I, THOMAS REEsE, of St.Louis, St. Louis county, State of Missouri, have invented a certainImprovement in Steam-Boiler Feeders, of which the following is aspecification:

The object of this invention is to introduce the feed-water ofsteam-boilers into a muddrum or other suitable settling-chamber, in sucha manner that the mud and sediment will be deposited in the same, and aclear and pure ater will be furnished to the boiler, and the deposit ofmud and the incrustation on the boiler-sheets be thereby prevented; andthis invention consists in the provision of a discharge-pipe runningabout centrally through the mud-drum, and having a number of horizontalside discharge-openings or branches, so as to discharge the watersidewise into the mud-drum in a number of streams having a very lowvelocity, so as to avoid the agitation of the mud and sediment thatnaturally settles in the lower portions of the mud-drum orsettling-chamber. The feed-water is preferably brought to saiddischarge-pipe by a vertical supply-pipe passing through theboiler-shell, and through the mud-leg of same, and is connectedcentrally to the discharge-pipe.

Figure 1 is a longitudinal section. Fig. 2 is a transverse section.Figs. 3 and 4. are detail perspective views of the discharge-pipe.

A is the boiler; B, the mud-drum, and O the mud-leg. D is adischarge-pipe, arranged centrally in the mud-drum, and provided with anumber of side discharge-openings or branches, d, through which thefeed-water flows sidewise into the drum in a number of streams of lowvelocity, so as not to agitate the mud and sediment that naturallysettles to the bottom of the mud-drum, and which is removed through theblow oft' pipes E, which, in a single boiler, are arranged at the endsof the mud-drum.

In a battery of two or more boilers the blow-ofi' pipes will beconnected to the bottom of the mud-drum opposite the mud-legs, so as toinsure a perfect removal of the mud and sediment in blowing ofl.

d are supporting-legs for the dischargepipe D. The number ofdischarge-openings 01 will vary according to the size of and number ofboilers used.

Instead of the openings cl, as shown in Figs. 1, 2, and 3, the pipe Dmay have small perforations 61 along its sides, as shown in Fig. 4.

F is the supply-pipe, connected either to the doctor or to asettling-chamber, G, as shown, and passing down centrally through theboiler-shell A and mud-leg O, and connected centrally to thedischarge-pipe D. The purpose of the pipe F passing through the boiler,as described, is to heat the water passing through it, and prevent thecold water coming in contact with the boiler-sheets. In tubular boilers,&c., where pipe F cannot be thus arranged, it may be brought in in anyconvenient manner.

When a settling-chamber G is used the feed-water is introduced into itthrough a supply-pipe, H, entering one end of the chamber near itscenter. The water, in passing through said chamber, deposits the greaterpart of its inud before being discharged through pipe I, connected withthe supplypipe F of the boiler.

The pipe I has a check-valve, I. The pipe H has side discharges orbranches h, (similar to the pipe D,) so as to permit the water to gentlyflow into the chamber without disturbin g its contents. K is asteam-pipe passing from the boiler to the top of chamber G, to supplysteam for blowing off the mud and sediment from said chamber, which isdone through the blow-off pipes 9, arranged as shown.

I claim as my invention- 1. The discharge-pipe 'D, having a number ofside discharge-openings,d, in combination with boiler A and 1nud-drum B,substantially as set forth.

2. The discharge-pipe D, having dischargeopenings d, in combination withthe mud-drum B, having blow-off pipes E, arranged substantially asdescribed.

3. The discharge-pipe D, having dischargeand vertical supply-pipe I1,substantially as g, in .combinatipnwwi-sh thesteam-pipeK, dis

discharge-pipe I, and supply-pipe H, having' Witnesses:
